Many technicians are very familiar with Biosan II and we would like to confirm usage and product details.
Biosan II is an anti-microbial decontaminant and hospital-grade disinfectant for use in surface disinfection and cleaning. Biosan II is used in hospitals, aged care homes, child care centres, schools, industry and medical laboratories. In fact, Biosan II is ideally suited to any application where disinfection and prevention of cross-contamination is critical. Biosan II is super versatile and exhibits serious cleaning power, making it a product that is gaining popularity fast.
The ultimate blend of high-activity biocides and quaternary ammonium compounds, plus the most advanced wetting technology, makes Biosan II incredibly effective as a disinfectant against a wide spectrum of micro-organisms.
The Biosan II formula has not been altered to achieve the new virucidal claims. The traditional use of Biosan II in mould remediation and bio-decontamination in terms of dilutions and mode of use remains unchanged.
Recommended usage directions based on microlab testing are;
Where COVID-19 specific disinfection is required
We have released a ready-to-use version of Biosan II which is mostly preferred in the healthcare sector.
To help distinguish between the concentrate (original Biosan II) and the ready-to-use version we will be making the concentrate a slightly darker tan/yellow.
Dwell time can best be achieved by not rinsing treated surfaces (clean surfaces only) and allowing to air dry.
Surfaces which are visibly dirty or/and contaminated must be rinsed with clear water after the given dwell time. Surfaces which are clean can be allowed to air dry which provides maximum disinfection action. However, excess moisture must be removed. Surfaces should not take longer than 30 minutes to air-dry.
At ready-to-use dilutions, Biosan II is safe to use on a wide variety of surfaces. Most water-cleanable surfaces are compatible with ready-to-use Biosan II. A few points to note are:
When diluted, Biosan II can be sprayed and fogged. Respiratory PPE must be worn by technicians and inhabitants must only be allowed to return after a minimum of 60 minutes. Possibly longer depending on ventilation characteristics.
The ingredients in Biosan II are all classified as safe for use in food preparation areas. However, it is not classified as a no-rinse sanitiser so surfaces must be rinsed with clear water or wiped dry.
Due to its TGA registration, certain label amendments were required which need to be read in the context of healthcare use which is TGA’s main focus. These statements are explained below;
